GMAT Critical Reasoning : (CR) Questions
During the Second World War, about 375,000 civilians died in the United States and about 408,000 members of the United States armed forces died overseas. On the basis of those figures, it can be concluded that it was not much more dangerous to be overseas in the armed forces during the Second World War than it was to stay at home as a civilian.
Which of the following would reveal most clearly the absurdity of the conclusion drawn above?

Argument Flow:
The argument starts with raw death statistics for two groups during WWII, then immediately jumps to a conclusion about relative danger levels based solely on comparing those total numbers.
Main Conclusion:
Being overseas in the armed forces during WWII was not much more dangerous than staying home as a civilian.
Logical Structure:
The argument uses a simple comparison of total death figures (375,000 vs 408,000) to conclude that danger levels were similar. However, this logic is flawed because it ignores the crucial factor of population size - we need to know how many people were in each group to determine the actual risk per person.
Prethinking:
Question type:
Weaken - We need to find information that would reveal the absurdity of concluding that being overseas in the armed forces wasn't much more dangerous than being a civilian at home, based solely on comparing raw death numbers.
Precision of Claims
The argument makes a quantitative comparison using raw death totals (375,000 vs 408,000) to draw a conclusion about relative danger levels between two different populations.
Strategy
The argument's flaw is comparing raw numbers without considering the size of each population. We need to think about what would expose this flawed reasoning. The key insight is that if the populations being compared are dramatically different in size, then raw numbers become meaningless for measuring relative danger. We should look for scenarios that highlight how population size affects the validity of this comparison.
Counting deaths among members of the armed forces who served in the United States in addition to deaths among members of the armed forces serving overseas: This doesn't address the core flaw in the argument. Adding more deaths to the armed forces total would just change the raw numbers being compared, but we'd still be stuck with the same fundamental problem of comparing raw totals without considering population sizes. This wouldn't reveal why the reasoning is absurd.
Expressing the difference between the numbers of deaths among civilians and members of the armed forces as a percentage of the total number of deaths: This is just a different way of presenting the same flawed comparison. Whether we say '\(\mathrm{375,000\,vs\,408,000}\)' or '\(\mathrm{about\,48\%\,vs\,52\%}\)' of total deaths,' we're still comparing raw numbers without accounting for how many people were actually in each group. This doesn't expose the absurdity of the logic.
Separating deaths caused by accidents during service in the armed forces from deaths caused by combat injuries: While this might provide interesting additional information, it doesn't address the fundamental flaw in comparing total death counts. We'd still be comparing raw numbers between different-sized populations, so this wouldn't reveal why the conclusion is absurd.
Comparing death rates per thousand members of each group rather than comparing total numbers of deaths: This is correct! This directly addresses the core problem with the argument. By calculating death rates per capita (deaths per \(\mathrm{1,000}\)' people), we can make a meaningful comparison between the two groups regardless of their different population sizes. If we knew there were, say, \(\mathrm{100\,million}\)' civilians but only \(\mathrm{10\,million}\)' armed forces members overseas, the death rates would be vastly different (\(\mathrm{3.75\,per\,thousand}\)' vs \(\mathrm{40.8\,per\,thousand}\)'), clearly revealing how absurd it is to conclude similar danger levels based on raw totals.
Comparing deaths caused by accidents in the United States to deaths caused by combat in the armed forces: This changes what we're comparing entirely - it's no longer about civilians vs armed forces members, but about accidents vs combat deaths. While this might be an interesting comparison, it doesn't address the flaw in the original argument's logic of comparing total death counts between different populations.
